RE: Brakes "sticking" '89 200 2wd

["Nicholas C. Craft" <ncc@scr.siemens.com>]

I had the same exact problem with our '89 200Q.
It was the master cylinder. It fails in such a way that it doesn't allow the 
brakes to disengage fully.
A new master cylinder from Blaufergnugen (1 800 683 AUDI) solved the problem.
You will find there are 2 possible MC's for your car - one has the lines coming
Out at a "V" angle, and the other they come out straight. Take a look at yours
Before you order. And don't buy one from the dealer unless you want to pay
3 times what you have to!

Good Luck,
Nick Craft

I have checked the archives but can't seem to find any helpful references
related to this problem.

I have a 89 200 2wd.  Sometimes in the middle of a freeway drive, my car
will "bog down".  It feels like I am driving against a very strong
headwind.  When I get home the front wheels are very hot, and I have
noticed over time a higher concentration of brake dust than was normal.

It sure seems that the front brake pads are applying pressure without any
brake pedal pressure; would this be called "unintended deceleration" : )

I can pump the brake or press hard on the brake, without any noticeable
improvement.  It seems to resolve on its' own in a random fashion.  My
questions:  where should I start, calipers, master cylinder, brake servo,
line bleeding, pressure accumulator, or the "bomb".

Have you ever heard of this type of problem?  Any help would be greatly
appreciated.  Post or Email
